Comet C/2012 S1 Ison: 3 Apr. 2013 image

CometC/2012 S1 “Ison” is still continuously monitored by astronomers worldwide, waiting for its potentially bright apparition later this year. The Virtual Telescope Project visited it again, after the full Moon moved away.

The image above comes from the average of 16 single exposures, each integrated for 300 seconds. For this, the PlaneWave 17 robotic unit was used. The telescope tracked the stars without any autoguiding. A little tail is very well visible.

If everyone reading this right now would donate something, our fundraiser would be done in a few days. Please, donate and receive stunning, LIMITED EDITION images with the Tiangong 1 and International Space Station above Rome and one of a potentially hazardous asteroid taken by the Virtual Telescope, specifically made for supporters like you!
